Answer:
B) x^2 - 3/ 3x
Step-by-step explanation:
As, f(x) - g(x) = x/3 - 1/x
So, x^2/ 3x - 3/ 3x
= x^2 - 3/ 3x
If the number is x, then 2*(x+3)-7=9 due to that you subtract the result of double of x+3. Adding 7 to both sides, we get 2*(x+3)=16. Next, we divide both sides by 2 to get x+3=8 and subtract 3 from both sides for our final result, x=5
Answer:
The equation of the line is;
y = 3x + 18
Step-by-step explanation:
We want to write the equation of the line through (-9,-9) and (-6,0)
we start by calculating the slope of the line
m = (y2-y1)/(x2-x1) = (0+ 9)/(-6+9) = 9/3 = 3
The general equation of the line is;
y = mx + c
y = 3x + c
To get c, we use any of the points
we substitute for example -6 for x and 0 for y
0 = 3(-6) + c
c = 0 + 18 = 18
So the equation of the line is;
y = 3x + 18
Answer:
You will have to pay $22.05.
Step-by-step explanation:
We can solve this problem by making a proportion:
4.78 gallons/11 dollars = 9.58 gallons/x dollars
By cross-multiplying, we can solve for x:
4.78x = 105.38
x = 22.05
